The wave function distributions of different phases. (a) Chern insulator, the density of states is located around the edge. (b) Normal insulator, there is no state at the edge. (c) Second-order topological insulator, which has a density of state peak corresponding to a zero-dimensional bound state at the four corners of the square. The sample size is 32 × 32.
